From 90ed31beac54f6380a78a4b3c51c8fab434db95b Mon Sep 17 00:00:00 2001 From: Patrick Georgi Date: Fri, 29 Jul 2016 18:37:56 +0200 Subject: intel/skylake: Enable signalling of error condition Testing for "devfn < 0" on an unsigned doesn't work, and i2c_bus_to_devfn returns an int (with -1 for "error"), so use int for devfn.
